First, the ink factor 1, the effect of ink viscosity The viscosity of the ink should match the printing speed. The viscosity of the ink is too high, and the adhesion to the plate cylinder is too strong. It is not conducive to scraping the excess ink of the plate by the squeegee, and the probability of printing the knives is high. The viscosity of the ink should be measured and controlled regularly during the printing process, usually measured every 20 minutes to 30 minutes. 2, the effect of ink drying The ink dries too fast and is prone to crusting. If the crust is not dissolved during the ink circulation, it will stick to the edge or the bottom of the knife once it comes into contact with the squeegee, resulting in a printed knives. If the ink circulation system uses an open ink tank, ink crusts and agglomeration are more likely to occur. In order to reduce the occurrence of such cutter line failure, the ink in the ink tank should be stirred frequently; an appropriate amount of slow drying agent should be added as needed; if necessary, a sealing cover can be added to effectively control and reduce the printing cutter line failure. 3, the impact of ink fineness The fineness of the pigment particles has a direct influence on the frequency of occurrence of the cut line. For example, the pigment particles used in the blue ink have high hardness, and it is difficult to achieve very fine particle size even after sufficient grinding, and it is easy to damage the scratching during the printing process. The knife or the effect of the ink scraping often causes a knife line failure when printing blue ink. 4, the impact of ink activity In the ink production process, a certain amount of active agent is generally added. The plate cylinder also has a certain activity after chrome plating. If the activity of the ink and the plate cylinder is too high, the active material will adhere firmly to the roller during printing, and the squeegee is difficult to scrape it to form a knife. line. At this time, the plate cylinder is first cleaned to remove the active material on the surface, and an activity slowing agent is added to the ink to eliminate the cut line. 5, the impact of ink quality When the ink is stored for too long, the solvent balance changes, causing the ink to dissolve, or the ink is mismatched and used improperly, causing a chemical reaction, which causes the ink to precipitate. During the printing process, the precipitate in the ink tends to accumulate at the doctor blade to cause the knife line, and the ink needs to be replaced.
